The inborn errors of immunity (IEIs) include genes with pathogenic variants that predispose not only to infections (immunodeficiencies) but also immune dysregulation (autoimmunity, lymphoproliferation, susceptibility malignancies). yin and yang, in the context IEIs, refers these seemingly opposing entities infection dysregulation. Over past decade or so, availability accessibility complex diagn...
The B7-CD28 immunoglobulin superfamily of costimulatory and coinhibitory ligands and their cell receptors play a critical role in modulating immune responses. Imbalances in these immune regulatory signals occur in pathological conditions characterized by chronic antigenic stimulation. Clinical studies often rely on the use of cryopreserved peripheral blood mononuclear cells (PBMC) to evaluate c...
Activated phosphoinositide 3-kinase (PI3K) δ Syndrome (APDS), caused by autosomal dominant mutations in PIK3CD (APDS1) or PIK3R1 (APDS2), is a heterogeneous primary immunodeficiency. While initial cohort-descriptions summarized the spectrum of clinical and immunological manifestations, questions about long-term disease evolution and response to therapy remain. The prospective European Society f...
In young adulthood, MRL/Mp-lpr/lpr mice develop severe systemic lupus erythematosus (SLE)-like syndrome associated with massive T cell proliferation. The congenic MRL/Mp- mice lack the lpr gene and develop chronic SLE late in life. We have exchanged thymic transplants between these substrains so as to determine the role of the thymus in the development of early, severe SLE and of lymphoprolif...
Background: In previous works we demonstrated that subcutaneous sensitization with Ovalbumin (OVA) induce generation of specific IgE antibodies and modifications of immune cells populations in different mucosal sites in rabbit. The aim of the study was the evaluation of OVA specific lymphoproliferation in mesenteric lymph nodes (MLNs), spleen and Peyer’s patch from OVA orally and subcutaneous s...
Prolactin (PRL) is involved in the regulation of immune functions under normal and pathological conditions. Trauma-hemorrhage (T-H) produces profound immunosuppression in male mice but not in proestrus female mice. Administration of PRL in males after T-H, however, restores immune functions. In this study, PRL(+/+) and transgenic (PRL(-/-)) male and female mice were used to assess immune suppre...
Primary and reactivated Epstein-Barr virus (EBV) infections after organ transplantation are associated with the development of posttransplant lymphoproliferative malignancies. Since viral reactivation frequently stays asymptomatic, early diagnosis and treatment are challenges during posttransplant patient monitoring. Both soluble-CD23 (sCD23) and intercellular adhesion molecule 1 (ICAM-1) cell ...
The expression of muH chain is an important checkpoint in B cell development. In mice deficient for IgM transmembrane tail exons (muMT mice) B cell development is blocked at the pro-B stage. However, we showed that Fas-deficient muMT mice (muMT/lpr) develop a very small population of isotype-switched B cells and produce high titers of self-reactive serum antibodies. In addition, muMT/lpr mice d...
